Narrative:

Leveling at FL370 we received a right engine fire EICAS message and warning. I retarded the throttle to idle and the warning ceased. Moments later we received the second fire warning. We executed the engine fire checklist. I used both fire bottles as the warning persisted after use of the first bottle. I sent the FSS manager to the area behind the right wing to check for fire or smoke. Non sighted. I decided to land at las as the nearest suitable airport. The landing was with the emergency equipment standing by. An inspection of the right engine, after clearing the runway by the emergency crew, found no evidence of fire. I taxied the aircraft to gate to deplane the passenger.
